Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution: a special-shaped bolt comprises a bolt column 1, wherein a head 2 is integrally formed at the outer end of the bolt column 1, an inner hexagonal groove 3 is formed in the end face of the head 2, a threaded hole 4 is formed in the bottom of an inner cavity of the inner hexagonal groove 3, a magnet plate 5 is arranged in the inner cavity of the inner hexagonal groove 3, and the threaded hole 4 is formed in the bottom of the inner cavity of the inner hexagonal groove 3, so that the special-shaped bolt can be connected with an external bolt under the condition that the inner hexagonal groove 3 is damaged due to long time, the external bolt is convenient to disassemble, and meanwhile, the magnet plate 5 can plug the threaded hole 4 to reduce the loss of the threaded hole 4;

the bolt column 1 includes that the figure of first short screw 7 and the short screw 8 of second is a plurality of, first

short screw

7 and 2 integrated into one piece in end, slot 9 has all been seted up to the one end of first short screw 7 and the short screw 8 of second, mounting groove 13 and slot 9 intercommunication have all been seted up to the outer wall of first short screw 7 and the short screw 8 of second, the other end of the short screw 8 of second is fixed with inserted bar 10, inserted bar 10 pegs graft in slot 9, install fastening bolt 12 in the mounting groove 13, fastening bolt 12 and inserted bar 10 screw-thread fastening are through the short screw 8 of increase and decrease second to can consider the length that realizes adjusting bolt column 1, make strong adaptability.
